Re: [PSES] Magnetic fields, human exposure standards, and pacemakers

Dan -- I'd suggest that you have your relative call Support at the pacemaker/defib manufacturer. On a slightly different project, I found a lot of on-line information about device immunity, and I think we even called Support and got additional clarifying information. Go to the source! Mike

Re: [PSES] Magnetic fields, human exposure standards, and pacemakers

Hi Dan, So the issue here is that pacemakers are designed to be stopped with the use of a permanent magnet. When the cardiologist is checking the operation of the pacemaker in the office, they will stop it by placing a permanent magnet on the chest of the patient. They can then see how the

Mains power lines running overhead make magnetic fields at 50/60 hertz…. I lived near Barcelona, Spain, for almost two years. The local trains used overhead lines. The stations used color CRT displays for train info. You could tell when a train was arriving as the display would distort

Re: [PSES] Magnetic fields, human exposure standards, and pacemakers

Recall from school that the H field roll off is third order.  The size of the magnets is small, about 1/8 inch on the ones I have.For comparison, the speaker magnetics in some smart phones are a bit larger and stronger.  And the phone NFC, near field communication, uses AC magnetic fields. Oh,

[PSES] Magnetic fields, human exposure standards, and pacemakers

Hello list! I have a relative with an implanted pacemaker/defibrillator who recently got a fitness tracker that has a magnet for attachment/alignment of the charging cord. There are warnings in the user manual advising against people with pacemakers using this product because of the magnets,
